SPECIFICATION forming part of Letters Patent No. 525,838, datedSeptember 1 1, 1894.

Application filed August 22, 1892. Serial No.443,688- (N model.)

To aZZ whom it may concern.-

Be it known that I, HIRAM M. BURDIOK, of Syracuse, in the county ofOnondaga, in'the State of New York, have invented new and usefulImprovements in Cultivators, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in cultivators, and has for itsobject the production of a simple and effective device, which isparticularly economical in manufacture, and practical and durable inuse; and to this end it consists, essentially, in a frame having acentral longitudinal bar and side frame bars on opposite sides of theformer bar having their rear ends movable toward and away from eachother, a head or block movable on the central frame bar, spreader barshaving their outer ends hinged to the rear ends of the side frame bars,and their inner ends crossed and secured to said head,

an actuating lever hinged to the frame, and a link hinged to theactuating lever and to said movable head.

The invention furthermore consists in a stationary head on the frame forsupporting the actuating lever for the movable head, a looking leverhaving one end hinged to the stationary head and the other adapted toengage the movable head, an actuating lever for disengaging the lockinglever, a land wheel actuating lever, a locking arm having a laterallyextending end engaging with a recess in, the stationary head, a lockingdog on the land wheel actuating lever for engaging the upper end of saidarm, ahandle brace passed through said stationary head above thelaterally ex tending end of the locking arm and clamped thereupon, andin the detail construction and arrangement of the parts, all ashereinafter more particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanyingdrawings, forming a part of this specification, in which, like lettersindicate corresponding parts in all the views.

Figure 1 is a side elevation of my improvedcultivator, illustrating thegeneral arrangement and construction of the parts. Fig. 2 is an enlargedhoaizontal sectional view, taken on line -2-2, Fig. 1. Fig. 3 is anenlarged vertical sectional view, taken on line 33, Fig. 2, the centralportion of the movable head actuating lever being broken away. Fig.

4 is a top plan view of the detached rear ends of the frame bars shownas in their position assumed when approximated, the spreader bars, andthe movable head for the spreader bars. Fig. 5 is a rear elevation,partlyin section, of the parts as shown at Fig. 4. Figs. 6, 7, 8, and 9are detail vertical sectional views, taken respectively on the sectionlines -66-, -77-, 88, and -9-9-, Fig. 3, further illustrating theconstruction and arrangement of the parts. Fig. 10 is a detached rearelevation of the movable head on the central frame bar, and Fig. 11 is aside elevation of the detached stationary head on said frame bar.

A represents the frame of my cultivator, here shown as composed of acentral bar aand side bars a'a on opposite sides of the bar a. Thecentral bar a is formed with an upturned arm a* provided with a seriesof perforations a, for receiving a bolt b that secures a clevis -B tothe arm a Suitably mounted upon the rear end of the bar a is a sation'ary head -O and directly in advance of the head O is a head E, which isalso suitably mounted on the bar a and is movable toward and away fromthe head O.

-A-A'- are clip plates arranged above and below the forward end of thecentral bar -a at the rear of its upturned arm a These clip plates crossthe bar a at substantially right angles, and consequently their endsproject laterally therefrom. Suitable shoulders A on the adjacent facesof the plates -A'-A and clamps -A A prevent the disengagement of saidplates and firmly secure them in position. Projecting from the adjacentfaces of the plates -AA' are rounding projections A A and in suitableproximity to these proj ections are rounding engaging shoulders A A Theforward ends of the side frame bars a'--a incline toward each other, andare formed with the laterally extending arms a -a which are interposedbetween the rounding projections A -A 7 spreader bar.

and the shoulders A of the corresponding ends of the clip plates AA.Consequently these shoulders A A and projections --A*A-- secure theforward ends of the side frame bars to the clip bars AA'-, and permit ofa hinge movement of the forward'end of said bars around the projectionsA A The rear ends of the bars --aa are formed with the outwardlyextending rounding faces a a and with upright eyes -a a at the rear ofsaid faces.

D--D-- are spreader bars, which each consist of a pair of separated barsarranged one above the other. The outer or rear ends of the bars -DD aresecured by bolts or other suitable clamps -d-d to the eyes a -a andtheir inner or front ends are crossed and secured by bolts or otherclamps d--dto upright eyes ee, which are formed upon arms E-E'-extending laterally from the opposite sides of the rear end of themovable head -E.

As clearly seen at Figs. 4 and 5 the top bearing face of the right handeye is lower than the corresponding bearing face of the left hand eye,and the lower bearing face of said right hand eye is lower than thecorresponding bearing face of the other eye in order that the inner endsof the bars of the right hand spreader bar may cross above thecorresponding ends of the bars of the left hand As also clearly seen atFig. 5 the upper bar of the right hand spreader bar is formed with adownward deflection, and the lower bar of the left hand spreader barwith an upward deflection in order that the rear ends of the bars ofeach of said spreader bars may be separated only a distancecorresponding to the height of the eyes a" The head E--, as previouslystated, is movable on the bar a, and, as it is forced forward orbackward, the rear ends of the frame side bars a cfiare moved toward andaway from each other, and their forward ends have a hinge movement uponthe clip plates -AA'.

-F--F-- are cultivator points, which are carried by suitable standardsor shanks -f-- f having their upper ends adjustably secured by clampsff--f'fto the forward ends of the side frame bars a'.-a

G- G- are cultivator points of somewhat difierent form from the previouspoints FF, and -gg are standards having their rear endsattached to saidpoints G- G- and their upper ends adjustably secured by bolts gg'-g-g'--to the rounding faces a a of the rear ends of the bars a' a G isacentral rear cultivator point attached or fastened to the lower end of ashank g having its upper end secured by clamps g to the rear end of thecentral frame bar -a.

H- is an actuating lever for forcing the head -E forward and backward toap proximate and separate the rear ends of the frame bars a'--a Thislever is preferably formed of a strip of sheet metal folded upon itself,and consequently consists of a pair of separated substantially parallelbars or legs joined at their upper or free extremity. The lower end ofthe lever H- is secured by a pivotal pin or bolt h to separated earsO'C- at the forward extremity of the head 'O-.

H' is a link formed also of a folded strip of sheet metal and composedof a pair of separated bars having their rear ends connected. The upperor rear end of the link H is hinged at h to the lever H- and its otherend is hinged at h to ears -E E upon the top face of the head --E-. Asthe upper end of the lever -H is forced forwardly and backwardly thehead E-- is positively and effectively moved in the same direction, and,as is evident, this peculiar construction of lever ll-- and link orconnection His particularly economical, light, strong, and durable.

-I is a locking lever or bar for holding the head -E--in its adjustedposition. The rear end of the locking lever or bar is, as best seen atFig. 3, formed with an inwardly extending groove orcutout i of lesswidth at its outer edge for receiving a forwardly projecting rib or barcon the front face of the head -C, and the under face of the front endof the locking lever or bar I- is formed with a series of teeth i'-- forengaging the pivotal pin h secured in the ears E E The rear end of thelocking lever I- is arranged between the separate bars of the actuatinglever -I-I, and its forward end is arranged between the bars of the linkor connection H'- and the ears E -E Consequently the locking lever I- isformed at its rear end with a transverse slot --I'- for receiving thepivotal bolt -h of the lever -H-. A suitable spring P- is arrangedwithin this slot -I with one end bearing against the under face of thebolt hand the other against the opposite wall of the slot I'-.

-I is an actuating lever pivoted at -z' to the upper end of theactuating lever -H, as best seen at Figs. 1, 2, and 3.

-1 is a connection or link formed of wire or other suitable materialhaving one end hinged to the actuating lever -I and the other passedbetween the bars of the actuating lever ITI and the connection H andhinged to an ear i arranged directly above the slot I. As the upper endof the lever I is forced toward the adjacent end of the lever -I-I theconnection I pulls the locking lever I- upwardly against the action ofthe spring I and disengages its forward end from the head E forpermitting adjustable movement of said head.

The described construction and arrangement of the locking lever, itsactuating lever, and the connections between the two are particularlyeconomical in manufacture, and practical and simple in operation, and,as will be readily apparent to one skilled in the art, thenaturalclosing of the hand to engage the upper end of the lever H- draws thelever 1 into position to disengage the locking lever from thehead topermit its movement by said lever -H.

-J is the land wheel, and jits support or standard, which also consistsof a pair of separate bars.

j is an opening extending through the support jand adapted to registerwith an opening a at the base of the arm a previously described. Therear end of the support or standard j is curved downwardly in a planeconcentric with the opening j'-, and is formed with a series ofperforations -j*. A bolt -j passes through the lower perforation j andthe central frame bar -a, thus pivoting the rear end of the land wheelsupport or standard to the frame. 7

-K- is an actuating lever for raising and lowering the land wheel byrocking its support or standard backwardly or forwardly. This lever alsoconsists, preferably, of a bar folded upon itself, and consisting of apair of substantially parallel bars joined at their rear ends and attheir forward ends with a downturned lateral arm 7c pivoted at Zc'-- tothe central frame bar a. A link L- is pivoted at Z to the lever K, andis hinged by a bolt Z to the upper perforation 9' -M is a locking arm orrack having its rear face disposed in a plane concentric with the pivot7c of the lever K-- and formed with engaging teeth m. At the lower endof the arm M- is a laterally extending lug -'m'-, which enters a recess-O opening inwardly from the rear face of the head -N is the handlebrace, which consists of upright arms n n and a connecting bar n betweenthe lower ends of the arms. This bar is passed through. a slot Oextending through the two opposite faces of the head O and arrangeddirectly above the lug m'-. Consequently the bar nrests upon the topface of the lug m', and is firmly forced thereagainst by a clamp orscrew C bearing against the upper face of said bar for firmly retainingin operative position both the handle brace N- and the locking arm -M-.Suitable handles --O- 0- are secured at 0- to the upper ends of thehandle brace arms n n-, and are also secured at their lower ends by abolt 0'- to the central frame bar a-. Since the lever K, as previouslystated, is composed of a folded bar, it is consequently formed with alengthwise slot or opening K' extending through its upper and loweredges between the separated bars of said lever. Mounted upon the topface of the rear end of the lever -K is a cap P-, which is formed withan ear pthat enters the slot K', and is secured to the lever by a rivetor other fastening means p'. The under face of this cap P, which restsagainst the top edges of the bars forming the lever K- is provided witha groove or cut-out 2 R is a dog having one end inserted within the slotK' beneath the cap P and provided with laterally extending arms p whichare mounted in the groove p that forms a bearing therefor, and rest uponthe top edges of the separate bars of the lever K. A suitable springS-is interposed between the rear end of the cap P- and the lever R forconstantly forcing the rear end of said lever R- away from the lever-K-. At the forward end of the dog R is a rounding laterally extendingrib r'-- adapted to engage the teeth of the upright arm M- for lockingthe lever -K to said arm. This rib is of sufficient length so that itsends bear against the under side of the lever -K and form a stop forlimiting the separation of the rear end of the dog R- from thecorresponding end of the lever K. As the lever K- is raised and loweredthe land wheel is readily adjusted, and by means of the dog R- saidlever is firmly held in its adjusted position. Moreover the parts ofthis land wheel adjusting mechanism are particularly simple, practical,and efiective.

Upon reference to the foregoing description and the accompanyingdrawings, it will be readily noted that the rear ends of the side framebars are readily adjusted toward and away from each other, and are thenfirmly held in their adjusted position, owing to the crossing of theinner ends of the spreader bars and the engagement of the locking leveror bar with the movable head carrying the spreader bars; that the landwheel is also readily adjusted and firmly held in position, and that theparts of my invention are extremely practical in construction andoperation, are readily assembled, and durable in use. It is evident,however, that the detail construction and arrangement of these parts maybe somewhat varied without departing from the spirit of my invention.
